The EDB Postgres Advanced Server must generate audit records when unsuccessful attempts to modify security objects occur.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-69041	PPS9-00-010900	SV-83645r2_rule		Medium

Description
Changes in the database objects (tables, views, procedures, functions) that record and control permissions, privileges, and roles granted to users and roles must be tracked. Without an audit trail, unauthorized changes to the security subsystem could go undetected. The database could be severely compromised or rendered inoperative. To aid in diagnosis, it is necessary to keep track of failed attempts in addition to the successful ones.
